Abstract: Spatial variability of rainfall–runoff and rainstorm–flood relationships are very important to water planning and utilization. Taking the mountainous area of Daqing River basin as the studied area, this paper reveals the ...

Abstract: Flow resistance is a critical calculation parameter in hydraulic engineering. In this study, the roughness coefficient of a circular drainage pipe with sedimentation was investigated under open-channel flow conditions using ...

Abstract: Polyurethane (PU) cutoff walls have increasingly been used in earth dam reinforcement projects due to their excellent antiseepage properties, strong deformation capabilities, ease of construction, and environmental ...

Abstract: Nonaqueous reaction foam polyurethane (PU) grouting materials have found wide applications in civil engineering. However, degradation laws and mechanism of the strength performance of PU grouting materials in different ...

Abstract: Polyurethane grouting technology has been applied in the maintenance and reinforcement of transportation infrastructure such as airports, expressways, and high-speed railways. For rigid pavements with voids underneath ...
